1 Claim.

This invention relates to a paring and coring tool and is designed to provide an auxiliary or additional bearing surface in conjunction with the blade thereof for coaction with the finger of the user when operating the tool, and constructed to overcome any tendency of the fore or index finger of the user to slip or become fatigued during such use.

With the above and other objects in View, as will be apparent, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevational view of a paring and coring tool embodying the features of this invention.

Fig. 2 is a bottom plan view of the same.

Fig. 3 is a vertical section taken on line 33 of Fig. 1.

In the use of devices such as paring and coring tools and the like, the fore or index finger of the user bears upon the trailing or rear edge of the blade adjoining the handle and in the course of continued use the relatively abrupt edge of the blade tends to pinch and irritate the finger of the user. The present invention has in view the provision of a relatively wide guard or bearing in conjunction with the rear edge of the blade adjoining the handle so that a relatively large curved bearing surface is created for the fore or index finger of the user in operating the knife.

Reference being had more particularly to the drawing, I0 designates a blade having transversely convergent sides II and I2 to the inner end of which is connected a handle I3. The inner end of the blade is provided with integral wings or collar-forming members I4 adapted to encircle a cap or ferrule I5, mounted on the adjacent end of the handle I3. Attachment of the wings I4 and the ferrule I5, in rigid assembly with the handle I3 may be established through any suitable means, such as tacks or screws I6.

The line of convergence of the sides II and I2 of the blade extends forwardly from the ferrule end of the handle I3 in substantial longitudinal alignment with the side of the handle as shown in Fig. 1. Adjoining the line of convergence, the side II of the blade is struck outwardly to form a longitudinal cutting segment H which may be Adjoining the handle I3, the edge of the side 6 II of the blade (which is in trailing relation to the cutting segment I? on the side I2 of the blade) is provided with an upstanding ear 20. The body of the ear 2!] is preferably dished or curved inwardly from its forward edge to its handleward edge to provide a bearing surface substantially conforming to the contour of the finger of the user. It will also be observed that the blade side I I and ear 2!! (as shown in Fig. 3) provides angularly related outer surfaces or bearings corresponding to the angle of normal fiexure defined by the inner surface of the last and next to the last joint of an operators forefinger when flexed into gripping position thereon.

If desired, the surface of the handle adjoining 20 the inner or ferrule end thereof may be provided with ridges 2I of any suitable shape to present added means for preventing slippage of the hand thereon in either direction.

From the foregoing it will be apparent that the present invention provides a coring and paring tool having as an integral part thereof a bearing for coaction with the finger of the user which will relieve irritation and fatigue of the fore or index finger of the user, and at the same time affords a device of this character which is capable of inexpensive, expedient production and assembly in mass quantities.

What is claimed is:

The combination with a blade having transversely convergent sides and a handle at one end thereof, a cutting segment struck from one of said sides in proximity to the line of convergence thereof, an upstanding ear projecting from the MYRON J. ZIMIMER.
